This image, combining data from two instruments aboard NASA's Mars Global Surveyor, depicts an orbital view of the north polar region of Mars. The ice-rich polar cap (the quasi-circular white area at ...

Mars has never looked more like a world in transition, with ice emerging as the quiet architect of its past and a crucial resource for its future. A new wave of NASA data is sharpening the picture of ...

Mars may look like a dry and dusty world, but just beneath its surface lies one of the most surprising discoveries in planetary science. Stretching for hundreds of miles along the planet’s equator is ...

Hints of buried water on Mars have swung between tantalizing and controversial, but one idea keeps resurfacing: lakes could persist if they sit beneath a protective lid of ice. Instead of needing a ...

Changes in Mars’ axial tilt (obliquity) drive shifts between polar ice caps at low obliquity and widespread mid-latitude glaciation at high obliquity. These cycles result in ice accumulating inside ...

The warmest parts of Mars host a strange, thick layer of ice beneath the surface, and we may have finally figured out how it got there. It might have been shifted from the inside of the planet by ...

Using a satellite to peer beneath layers of dust and ice at Mars’ south pole, scientists have detected a 12-mile-wide span of briny water, a large, stable reservoir akin to lakes buried beneath the ...

UNIVERSITY PARK, Pa. — Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the Red Planet. By recreating Mars-like conditions in the lab, ...

Visit ancient Mars—a surprisingly temperate planet where snow or rain falls from the sky, and rivers rush down valleys to feed hundreds of lakes. A new study from geologists at the University of ...

An artist's impression of the Mars Express spacecraft probing the southern hemisphere of the planet. Using a satellite to peer beneath layers of dust and ice at Mars’ south pole, scientists have ...
